海南钻喙兰种质资源现状调查
结合路线调查法、踏查法、访查法,对海南全岛的海南钻喙兰资源现状展开调查与分析,调查地点涉及海南130多个乡镇,超过海南乡镇行政单位数量的2/3,结果发现22个海南钻喙兰种群,主要分布于海南白沙、琼中、五指山、儋州、乐东、昌江、东方、乐东、保亭、陵水等县市。海南钻喙兰多生长于海拔40~700 m通风良好、空气湿润、光线充足的沟谷或山谷疏林里的高大乔木上;其附主植物有17种,覆盖13科15属,附生高度在0.5~15 m。海南钻喙兰所生长的群落中,建群种主要有枫香、重阳木、木棉、芒果、山牡荆等树种。评估了海南钻喙兰在海南地区的濒危等级,分析其濒危原因,并提出相应的保护建议。...

After finishing the surveys of more than two-thirds of the towns in Hainan(more than 130 towns), 22 populations of R. gigantea have been found, they distributed mainly in Baisha, Qiongzhong, Wuzhishan, Danzhou, Ledong, Changjiang, Dongfang, Baoting, Lingshui. It likes growing on tall trees that grow in well-ventilated, moist and well-lighted valley at elevations between 40 and 700 meters. The phorophytes species include 17 species belonging to 15 genera and 13 |
